6.2.2.3 I/O Interface
This interface is used to communicate with a sequencer, a PC (programmable controller), or
relay circuitry by means of sequential signals. The signal has negative-true logic (output level
is LOW when control is ON). (Only Err-0 has positive-true logic.)

NOTE 1. This is internally wired to I.C. Always retain this pin externally unused.
2. Between Pin No.8 and Pin No.32, and between Pin No.15 and Pin No.26 are
connected internally, therefore outputting the identical signals. Only use either of
the pins.
3. In simultaneous measurement GO/NG judgment result from the program Nos.0 to
4 will be outputted to A-(-NG), A-(GO), and A-(+NG), and that from the program
Nos.5 to 9 will be outputted to B-(-NG), B-(GO), and B-(+NG), respectively.
4. In single measurement identical judgment results will be outputted to A-(-NG) and
B-(-NG), A-(GO) and B-(GO), and A-(+NG) and B-(+NG).
5. When group judgment is done, each individual judgment result will be outputted
for A-(-NG), A-(GO), and A-(+NG), and the group judgment result will be outputted
for B-(-NG), B-(GO), and B-(+NG), respectively.
